Why another control standard?
• OCA is the only control architecture that is all of the
following:
– Pro application oriented
– Scalable up to huge network sizes
– Suitable for mission-critical applications
– Compatible with proprietary product features
– Futureproof
– Secure
– On track to become an open public standard.

OCA In Action: Concert tour
Concert tour sound system
•
Touring system, possibly incorporating equipment from prime contractor and various
subcontractors.
•
Multiple ad-hoc connections, varying from place to place, ideally using network
audio. For example:
–
–
–
Prime contractor provides main loudspeakers, subcontractors provide delay
systems, fills, woofers, etc.
Connected to resident venue system for area fill.
Connected to show video systems, radio, TV,& internet broadcast systems,
recording systems, & press.
•
System configured modularly, with multiple mix and loudspeaker/ amplifier
subystems, variously deployed from rental house(s) for different tours.
•
Media transport may be mix of Ethernet, AES3, MADI, AVB, Dante, etc.
OCA Central wired & wireless control of multiple network(s).
Benefits Multivendor support. High reliability. Media flexibility.

OCA In Action: Large Install Venue
Large installed sound system
•
•
•
•
•
•
•
•
Example: stadium, multipurpose arena, large auditorium
Multiple program sources, control stations, loudspeaker clusters, and external
interfaces.
Interfaces to paging, signage, security, emergency (fire), show video, security, and
other internal systems.
Interfaces to external systems - broadcast, internet, user devices (tablet,
smartphone).
Evacuation standards compliance may be required.
Security may be required.
Network infrastructures are typically administered by central IT.
Large to very large network diameters.
OCA Control of large & complex networks. Security. Public
Benefits standards compliance for Evac. Multivendor systems.

OCA In Action: Broadcast Intercom
Network Broadcast Intercom System
•
•
•
•
•
•
•
•
•
•
Example: major television network production intercom
Thousands of intercom stations, multiple control points.
Transcontinental networks using private leased data lines.
Interfaces to broadcast mixing equipment.
VoIP interfaces
Portable and fixed-location stations.
Many subnets - multiple sites, multiple work environments within buildings, multiple
remote locations.
Network infrastructures may be administered by production intercom departments or
by central IT.
Frequent reconfiguration.
Critical function - must not fail (millions of dollars at stake)
OCA High reliability. Much simplified cabling. Ability to use
Benefits corporate network(s). Multivendor systems.

Benefits of OCA
• Interoperability
– Third party manufacturers can add value to your systems.
– You can sell into other systems you did not originally supply.
• OCA is open and freely available.
– Royalty-free
– Alliance membership NOT required.
– Specific software development kit NOT required.
• Reduced time to market and engineering cost.
– OCA is an already engineered and proven architecture.
• As OCA is adopted, a helpful OCA ecosystem will arise.
• Some big customers require compliance with public standards.
• Self-certification program → No added costs for 3d-party testing.

OCA Implementations
• One full-scale professional-grade
implementation is available (not free).
• Collaborative work is proceeding on a "lite"
implementation.
• Some of this work may lead ultimately to an
open-source implementation.
